Yellowing/Dying Leaves

[Raoul Duke]

Sure this isn't a phosphorus def? Seems to be pretty accurate:

A cannabis phosphorus deficiency generally appears on leaves from the lower/older parts of the plant. The lower leaves may turn dark green or yellow, and start getting spots or big splotches that look brown, bronze or even a little blue. The leaves may thicken and curl, and the affected leaves feel stiff. Sometimes the stems of the plant turn bright red or purple, but not always.

A bunch of my stems are red, lower leaves being affected, leaves turning yellow with splotches. And the leaves do feel a little stiff.

@Waira any thoughts?

Thanks for your help everyone

RD- that looks like some early P defc. to me,.. and from what I see in your inputs, you need more P-K, less N,... now is the time for PK boosters! if you're blending grow/bloom equally, 4-6-9 is not the best ratio, and that Ca-Mg is adding more unwelcome N on top of this, albeit a smaller amount,... lose the grow, get a PK booster (something with little to no N, and high P-K#'s, like KoolBloom 0-10-10) to use along with the bloom,.. keep in mind, it's not *(oops!) so much about the concentration of the nutes , especially since you found your burn-point, it's the ratios of N:K,.... easy enough to dilute down- ..and bro', don't remove the leaves, they are sources of stored nutes, this is in part why the start to look like hell... mobile nute elements can be removed for use on the new growth/buds,...

Thanks for the input!!! Ive ditched the grow nutes. Were on full bloom nutes. U think bloom boosters are completely necessary? Was trying to keep it simple for my first grow, but ill pick some up soon if that that'll do the trick. In terms of taking the leaves off, they're more falling off with very little pressure, but ill stop touching them haha!!! Thanks for gettingback to me.

I should also mention that the taller plant is only like 5 or inches away from the light and the other is a little less than a foot. Would this exacerbate the situation as well?

Would the botanicare hydroplex okay? 0-10-6

...necessary, no, just faster to egt available P-K in there right away,.. and depending on her size and therefore demand, maybe dilute regular inputs,.. this is what I often do with my outdoor photo girls,... sure, the Hydroplex will do,...
Whoa! for sure the lights are too close, about 18" min. from tops,.. I don't see signs of trouble, but it certainly can be a factor!
...yup, tapped out leaves will shed naturally,... no need to cut them out beforehand...

Hell yeah, thanks for the knowledge bomb @Waira

Will pick up some hydroplex tomorrow and a soil ph stick. Gonna see how they take their last feed and maybe add some hydroplex next feed. Unfortuneatly i cant do anything about the lights, they're as high as my tent will allow. No touching leaves, CHECK!!!

Quick update. Just checked on the ladies and no new yellowing leaves for now... Can rest a little easier

proximity alone will cause light stress/burn, and at that range, the color spec's have not blended well at all,... each diode is putting out only one wavelength I believe,.., but it's moot since your max'ed out anyway, next time, do some LTS or supercropping to keep tops at OK levels,... if you keep growing in soil/soilless (peat, coco), get an Accurate soil pH probe for in-pot measurements,... the meter is for liquids only,....
